to make it work, one must comment out or remove the following in bitcoinrpc.cpp:

    acceptor->open(endpoint.protocol());
    acceptor->set_option(boost::asio::ip::tcp::acceptor::reuse_address(true));

    // Try making the socket dual IPv6/IPv4 (if listening on the "any" address)
    boost::system::error_code v6_only_error;
    acceptor->set_option(boost::asio::ip::v6_only(loopback), v6_only_error);

    acceptor->bind(endpoint);
    acceptor->listen(socket_base::max_connections);

    RPCListen(acceptor, context, fUseSSL);
    // Cancel outstanding listen-requests for this acceptor when shutting down
    StopRequests.connect(signals2::slot<void ()>(
                static_cast<void (ip::tcp::acceptor::*)()>(&ip::tcp::acceptor::close), acceptor.get())
            .track(acceptor));

    // If dual IPv6/IPv4 failed (or we're opening loopback interfaces only), open IPv4 separately
    if (loopback || v6_only_error)

then it does:

and so on
